A candle under an inverted jar goes out and water rises inside the jar. Which statement is an inference rather than an observation?
- The water level rose by 1.5 cm.
- The flame went out after 12 s.
- The flame went out because the oxygen was used up.
- The inside of the jar became misty.

Answer: C
Options A, B and D report what was seen or measured. Option C proposes a cause that was not directly observed, so it is an inference that needs testing.
An original practice example, not a prediction of a future exam question.
